The aluminum extrusion motor body formed by hot extrusion has the advantages of light weight, high strength, good heat dissipation performance, beautiful surface, corrosion resistance, no cutting in the inner chamber, etc. Because of the poor concentricity between the shell and the end cover in the traditional processing of aluminum profile of motor shell, the motor running noise of aluminum alloy shell is large. According to the processing method of the aluminum profile of the motor shell, a processing tool for the aluminum extrusion motor bodyis designed. The aluminum extrusion motor body can be processed by two end stops of the aluminum extrusion motor body after one clamping. The concentricity of the inner hole of the aluminum extrusion motor bodyis ≤ 0.02mm, which can improve the production efficiency by more than one time, and solve the problem of large noise of the aluminum profile motor of the motor shell.
Aluminum extrusion motor body
Special processing tools for extrusion products
Common performance data of aluminum profile of motor shell:
Material brand: 6063-T5
Surface: untreated, anodized, electrolytic colored
Inner diameter working difference: ≤ 0.0007 D; roundness ≤ 0.0012d
The extruded aluminum motor shell housing produced by Henan Chalco are also used for: micro motor case, environmental protection air conditioning motor case, cooling fan motor case, water-cooling air conditioning motor case, air compressor motor case, negative pressure fan, motor case, electric vehicle motor case, tricycle motor case, servo motor special case, injection molding machine motor, cooling tower motor, cylinder, axial flow wind Machine motor, electric tool motor, reducer motor, etc.
Henan Chalco has successfully developed a unique special processing tool for extrusion products. Its deep processing quality occupies a significant position in the field of deep processing of motor shell aluminum profile products in China. It has successfully solved the problems such as springback deformation after adjusting the inner hole of motor shell aluminum profile and the unevenness in the process of deep processing of products, so as to provide a more perfect end for the majority of motor manufacturers Polar products.
